I just built a MicroATX Computer with 19" LCD Screen and a 4ch DVR that runs at 120FPS total. so i should have plenty

Got 3CCTV Cameras i use and move around all the time doing wildlife research. I need the 3 of them to come in so i can watch them all at once and record each individually.

I guess my only option is to buy a computer and make it into a DVR

Gah, i need it to be portable, so either i gotta find a decent USB one Or build a comp with a DVR Card..

Is there one out there that isnt that expensive - that one is around $500

Ok, i am looking for a good USB DVR I can use.. I need it to be portable so i am using laptop so i cant use a PCI Card. Will only be running 3 cameras so it wont be an extremely heavy workload.. Ive seen a couple of the USB DVR's but with 3 cameras it only ran at like 5 FPS.. Anyone know of a decent one?
